Safety of an extended-release injectable moxidectin suspension formulation (ProHeart^® 12) in dogs.

ABSTRACT:

Background

The safety of ProHeart® 12 (PH 12; extended-release injectable suspension; 10% moxidectin in glyceryl tristearate microspheres) was evaluated in four studies using Beagle dogs and one study using ivermectin-sensitive Collies. The recommended dose is 0.5 mg/kg subcutaneously once yearly.

Methods

Study 1: safety margin was evaluated as 3 treatments of PH 12 (0× (control); 1× (recommended dose); 3× (3 times recommended dose) and 5× (5 times recommended dose) in 12 months via clinical observations, body weights, food consumption, injection site observations, physical examinations, moxidectin tissue assay, pharmacokinetics, and clinical and anatomic pathology. Study 2: safety in breeding-age males was demonstrated by semen testing at 14-day intervals from Day 7 to Day
